Abstract: The authors propose a so-called life-span simulator that can predict concrete structural behaviors under arbitrary external forces and environmental conditions.
In order to realize this kind of technology,two computational systems have been developed;one is a thermohygro system that covers microscopic phenomena in C-SH gel and capillary pores,and the other one is a structural analysis system,which deals with macroscopic stress and deformational field.
In this paper,the unification of mechanics and thermo-dynamics of materials and structures has been made with the ion transport of chloride, CO(2) and O (2) dissolution.
This proposed integrated system can be used for simultaneous overall evaluation of structural and material performances without distinguishing between structure and durability.
